To improve the merchantability of a ship propulsion system.SOLUTION: This ship propulsion system comprises: a ship propulsion device; a battery; and a controller. The ship propulsion device includes a propeller shaft, an engine, and an electric motor. The ship propulsion device transmits a motive force from at least one of the engine and the electric motor to the propeller shaft. The battery supplies power to the electric motor. The controller controls the ship propulsion device so as to be able to switch a mode among a plurality of drive modes of the ship propulsion device including a first drive mode for transmitting only the motive force of the engine to the propeller shaft and a second drive mode for transmitting only the motive force of the electric motor to the propeller shaft in a state where the engine is in an idling state.SELECTED DRAWING: Figure 4

    【課題】船舶推進システムの商品性の向上を図る。【解決手段】船舶推進システムは、船舶推進装置と、バッテリと、コントローラとを備える。船舶推進装置は、プロペラ軸と、エンジンと、電動モータとを含む。船舶推進装置は、エンジン及び電動モータの少なくとも1つからプロペラ軸に動力を伝達する。バッテリは、電動モータに電力を供給する。コントローラは、エンジンの動力のみをプロペラ軸に伝達する第1駆動モードと、エンジンがアイドリング状態で電動モータの動力のみをプロペラ軸に伝達する第2駆動モードとを含む船舶推進装置の複数の駆動モードを切り換え可能に船舶推進装置を制御する。【選択図】図4
